One city, dozens of microclimates. A deck in the hills and a deck near the water are different problems.
The mountainous terrain around Los Angeles gives the area a large number of distinct microclimates, with extreme variations in temperature over surprisingly short distances. That is not a talking point, it is a specification problem. A deck in a hillside canyon, a deck a few miles inland baking through summer, and a deck close enough to the water for salt to reach it are three different sets of conditions, and the same coating is not the right answer for all three.
Only about 36 percent of housing units in Los Angeles are owner occupied, so the majority of what we do in the city is income property: shared walkways, open stairwells and stacked balconies where a failure travels down through the building rather than staying put.
We look at where the property actually sits before specifying. Sun exposure, wind, proximity to the water and how the water leaves the deck matter more to how long the repair lasts than anything printed on the bucket.
